01 / The Problem

Household demand peaks after solar generation peaks.

Millions of households charge cars after work and run dishwashers after dinner, as solar generation falls. Grid operators dispatch higher-emission plants to meet that evening demand and may curtail solar at midday when demand cannot absorb the available supply.

    12 PM

    Midday solar approaches demand.

    23,074 MW solar against 25,063 MW of demand.

  2. 02

    7 PM

    Evening demand peaks as solar falls.

    36,080 MW demand, with solar down to 7,271 MW.

  3. 03

    8 PM

    Demand stays high as solar falls to 188 MW.

    At 8 PM, demand remains 35,011 MW.

    GreenAI moves the flexible load out of that gap.

One recorded CAISO day. Hourly averages. Small negative overnight solar readings are clamped to 0 for display. Read the methodology and limitations.

Reading the chart

California's peak demand occurs hours after peak solar generation. Grid operators dispatch natural gas plants and other carbon-heavy generators to serve demand outside peak solar hours. Households can cut emissions and ease peak demand by moving flexible energy use to lower-carbon grid hours. GreenAI schedules those shifts around device deadlines.

02 / Device scheduling

GreenAI schedules devices by grid carbon intensity.

You set a ready-by time for each device. GreenAI uses your local grid's hourly emissions data to schedule flexible energy use before the deadline.

Simulated schedule for the prototype household. Device times and the carbon curve are illustrative, not measured. GreenAI holds each run inside the 12:00 AM–6:00 AM clean window unless a comfort deadline puts it elsewhere.

  1. 01

    Grid carbon by hour

    GreenAI compares carbon-intensity data from Electricity Maps with household load profiles from NREL ResStock to identify lower-carbon hours.

  2. 02

    Cross-brand scheduling

    GreenAI schedules EV charging and connected appliances across manufacturers through platforms such as SmartThings.

  3. 03

    Ready-by scheduling

    You set a ready-by time. GreenAI chooses a lower-carbon window that meets the deadline.

  4. 04

    Virtual power plant

    GreenAI can coordinate load shifts across thousands of participating households to reduce peak demand and the need for standby generation.

Modeled reduction: 35 of 100 household-emissions units

We modeled household load-shifting with CAISO hourly emissions data. No GreenAI field deployment has measured this result.

03 / The Product

Try the prototype live

That's the prototype's own dashboard, drawn from the same device list and the same CAISO day this page charts rather than from a screenshot. Open it and the schedules, the deadlines and the grid-cleanliness readout all run live in your browser. The only thing missing is the connection to a real home.

GreenAI is coordinating 4 of 5 devices in this simulation. Grid carbon intensity is in the excellent band.
